三种SQL分页查询的存储过程代码

复制代码 代码如下:

–根据MAX(MIN)ID

CREATE PROC [dbo].[proc_select_id]

@pageindex int=1,–当前页数

@pagesize int=10,–每页大小

@tablename VARCHAR(50)=”,–表名

@fields VARCHAR(1000)=”,–查询的字段集合

@keyid VARCHAR(50)=”,–主键

@condition NVARCHAR(1000)=”,–查询条件

@orderstr VARCHAR(500),–排序条件

@totalRecord BIGINT OUTPUT–总记录数

AS

IF ISNULL(@orderstr,N”)=N” SET @orderstr=N’ ORDER BY ‘+@keyid+N’ DESC ‘

IF ISNULL(@fields,N”)=N” SET @fields=N’*’

IF ISNULL(@condition,N”)=N” SET @condition=N’1=1′

DECLARE @sql NVARCHAR(4000)

–IF(@totalRecord IS NULL)

–BEGIN

SET @sql=N’SELECT @totalRecord=COUNT(*)’

+N’ FROM ‘+@tablename

+N’ WHERE ‘+@condition

EXEC sp_executesql @sql,N’@totalRecord INT OUTPUT’,@totalRecord OUTPUT

–END

IF(@pageindex=1)

BEGIN

SET @sql=N’SELECT TOP ‘+STR(@pagesize)+N’ ‘+@fields+N’ FROM ‘+@tablename+N’ WHERE ‘+@condition+N’ ‘+@orderstr

EXEC(@sql)

END

ELSE

BEGIN

DECLARE @operatestr CHAR(3),@comparestr CHAR(1)

SET @operatestr=’MAX’

SET @comparestr=’>’

IF(@orderstr<>”)

BEGIN

IF(CHARINDEX(‘desc’,LOWER(@orderstr))<>0)

BEGIN

SET @operatestr=’MIN’

SET @comparestr='<‘

END

END

SET @sql=N’SELECT top ‘+STR(@pagesize)+N’ ‘+@fields+N’ FROM ‘+@tablename+N’ WHERE ‘+@keyid+@comparestr

+N'(SELECT ‘+@operatestr+N'(‘+@keyid+N’) FROM ‘+@tablename+N’ WHERE ‘+@keyid

+N’ IN (SELECT TOP ‘+STR((@pageindex-1)*@pagesize)+N’ ‘+@keyid+N’ FROM ‘+@tablename+N’ WHERE ‘

+@condition+N’ ‘+@orderstr+N’)) AND ‘+@condition+N’ ‘+@orderstr

EXEC(@sql)

END

GO

–根据ROW_NUMBER() OVER

CREATE PROC [dbo].[proc_select_page_row]

@pageindex INT=1,–当前页数

@pagesize INT=10,–每页大小

@tablename VARCHAR(50)=”,–表名

@fields VARCHAR(1000)=’*’,–查询的字段集合

@keyid VARCHAR(50)=”,–主键

@condition NVARCHAR(1000)=”,–查询条件

@orderstr VARCHAR(500),–排序条件

@totalRecord BIGINT OUTPUT–总记录数

AS

IF ISNULL(@orderstr,N”)=N” SET @orderstr=N’ ORDER BY ‘+@keyid+N’ DESC ‘

IF ISNULL(@fields,N”)=N” SET @fields=N’*’

IF ISNULL(@condition,N”)=N” SET @condition=N’1=1′

DECLARE @sql NVARCHAR(4000)

— IF @totalRecord IS NULL

— BEGIN

SET @sql=N’SELECT @totalRecord=COUNT(*)’

+N’ FROM ‘+@tablename

+N’ WHERE ‘+@condition

EXEC sp_executesql @sql,N’@totalRecord bigint OUTPUT’,@totalRecord OUTPUT

–END

IF(@pageindex=1)

BEGIN

SET @sql=N’SELECT TOP ‘+STR(@pagesize)+N’ ‘+@fields+N’ FROM ‘+@tablename+N’ WHERE ‘+@condition+N’ ‘+@orderstr

EXEC(@sql)

END

ELSE

BEGIN

DECLARE @StartRecord INT

SET @StartRecord = (@pageindex-1)*@pagesize + 1

SET @sql=N’SELECT * FROM (SELECT ROW_NUMBER() OVER (‘+ @orderstr +N’) AS rowId,’+@fields+N’ FROM ‘+ @tablename+N’) AS T WHERE rowId>=’+STR(@StartRecord)+N’ and rowId<=’+STR(@StartRecord + @pagesize – 1)

EXEC(@sql)

END

GO

–根据TOP ID

CREATE PROC [dbo].[proc_select_page_top]

@pageindex INT=1,–当前页数

@pagesize INT=10,–每页大小

@tablename VARCHAR(50)=”,–表名

@fields VARCHAR(1000)=”,–查询的字段集合

@keyid VARCHAR(50)=”,–主键

@condition NVARCHAR(1000)=”,–查询条件

@orderstr VARCHAR(500),–排序条件

@totalRecord BIGINT OUTPUT–总记录数

AS

IF ISNULL(@orderstr,N”)=N” SET @orderstr=N’ ORDER BY ‘+@keyid+N’ DESC ‘

IF ISNULL(@fields,N”)=N” SET @fields=N’*’

IF ISNULL(@condition,N”)=N” SET @condition=N’1=1′

DECLARE @sql NVARCHAR(4000)

–IF(@totalRecord IS NULL)

–BEGIN

SET @sql=N’SELECT @totalRecord=COUNT(*)’

+N’ FROM ‘+@tablename

+N’ WHERE ‘+@condition

EXEC sp_executesql @sql,N’@totalRecord INT OUTPUT’,@totalRecord OUTPUT

–END

IF(@pageindex=1)

BEGIN

SET @sql=N’SELECT TOP ‘+STR(@pagesize)+N’ ‘+@fields+N’ FROM ‘+@tablename+N’ WHERE ‘+@condition+N’ ‘+@orderstr

EXEC(@sql)

END

ELSE

BEGIN

SET @sql=N’SELECT TOP ‘+STR(@pagesize)+N’ ‘+@fields+N’ FROM ‘+@tablename+N’ WHERE ‘+@keyid

+N’ NOT IN(SELECT TOP ‘+STR((@pageindex-1)*@pagesize)+N’ ‘+@keyid+N’ FROM ‘

+@tablename+N’ WHERE ‘+@condition+N’ ‘+@orderstr+N’) AND ‘+@condition+N’ ‘+@orderstr

EXEC(@sql)

END
